Blister beetle larvae, specifically Meloe proscarabaeus, exhibit an intriguing method of attraction by emitting floral-scent-like volatile compounds to lure bees. This first-known instance of chemical mimicry allows larvae to gain access to bee nests by hitching rides with visiting bees. Researchers from the Max Planck Institute for Chemical Ecology identified specific monoterpenoid volatiles, including the enantiomer of linalool, which mimics the floral scent that bees prefer. This adaptation enhances their reproductive success by facilitating access to food and shelter.
